Update to speex-1.2rc1. This should be backward-compatible with
1.0.x versions. Pulseaudio (which I am working on) requires this version; moreover, the 1.0.x releases are deprecated. The ChangeLog is not kept up-to-date, but here are some highlights: 1.2rc1 -------- Again, this new releases brings many improvements. The RAM requirement for wideband has gone down drastically (i.e. more than 2x). A new resampler module has been added, providing arbitrary sampling rate conversion -- fast. The echo canceller has also been improved. A bug in 1.2beta1 that made the echo canceller unstable has been fixed. The echo canceller should now converge faster, be robust and tolerant of incorrect capture-playback synchronisation. The preprocessor has also been greatly improved. Not only should the quality be better, but it is now fully converted to fixed-point. At last, early TriMedia support (incomplete) has been merged. 1.2beta3 -------- The most obvious change in this release is that all the non-codec components (preprocessor, echo cancellation, jitter buffer) have been moved to a new libspeexdsp library. Other changes include a new jitter buffer algorithm and resampler improvements/fixes. This is also the first release where libspeex can be built without any floating point support. To do this, the float compatibility API must be disabled (--disable-float-api or DISABLE_FLOAT_API) and the VBR feature must be disabled (--disable-vbr or DISABLE_VBR). 1.2beta2 -------- This release adds support for acoustic echo cancellation with multiple microphones and multiple loudspeakers. It also adds an API to decorrelate loudspeaker signals to improve multi-channel performance. In the bugfix department, there are fixes for a few bugs in the echo canceller, jitter buffer and preprocessor. At this point, the API for 1.2 should be stable and only a few very minor additions are planned.
